//1. Get a list of products that have been added to the cart for the given email (from the db)
IList <CartViewModel> cartEntries = _cartsRepo.GetCartEntries(email).ProjectTo <CartViewModel>(_mapper.ConfigurationProvider).ToList <CartViewModel>();
//2. loop within the list of products to check qty from the stock
//Stock not showing up on the intellisense so I can't test with it
foreach (var cart in cartEntries)
{
if (cart.Product.Stock < cart.Quantity)
{
throw new Exception("Not enough stock for product " + cart.Product.Name);
}
//if you find a product with qty > stock - throw new exception not enough stock
}
//3. Create order
Guid orderId = Guid.NewGuid();
Order newOrder = new Order();
newOrder.Id = orderId;
newOrder.DatePlaced = DateTime.Now;
newOrder.UserEmail = email;
//Contineu setting up other properties
//Might need to comment to test
_orderRepo.AddOrder(newOrder);
//3.1. Call the Addorder from inside the IOrdersRepository (this can be merged with step 3)
//4. loop with the list of products and create an OrderDetail Instance for each of the products
//Start of loop
foreach (var cart in cartEntries)
{
//4.1
//deduct qty from stock
_productsRepo.EditProductQuantity(_mapper.Map <Product>(cart.Product), cart.Quantity);

//4.2 Loop Call the add orderDetail from inside the IOrderDetailsRepository (this can be merged with step 4)
//Might need to comment for testing
